@fzs, thanks for your bug fix inspiration!

Somehow in WP 6.4.2 it didn’t work for me.

When I removed $taxonomy->meta_box_cb === false it worked, but for all categories on all post types.

But since I only want to hide a specific custom category, I simply replaced it with $taxonomy->name === 'event-category'.

So the final modified version is this:

add_filter( 'rest_prepare_taxonomy', function( $response, $taxonomy, $request ) {
    $context = ! empty( $request['context'] ) ? $request['context'] : 'view';
    // Context is edit in the editor
    if( $context === 'edit' && $taxonomy->name === 'event-category' ){
        $data_response = $response->get_data();
        $data_response['visibility']['show_ui'] = false;
        $response->set_data( $data_response );
    }
    return $response;
}, 10, 3 );
